“In an era when dance has exploded thanks to social media, [Tricia] Miranda wanted to share her dance moves, unfiltered, with the rest of the world. So in 2014, she hired a videographer to tape her dance studio in the North Hollywood neighborhood of Los Angeles, with students performing her signature moves.” Her first video racked up 27 million views, a later one 41 million, and her YouTube channel now has a million subscribers.
